Crank was serviced about a year ago. Head unit just came back from getting a new keypad (I think they replaced the whole unit though). Has Q-rings installed.
Rings are 53/38. 130/110 BCD. Crank arms = 175mm. This is a solid unit, ready to roll. Comes with everything pictured (plus the wall charger). I am not riding much anymore as a surgical resident, thus the reason for the sale. $475 shipped.
